Chemical Engineering Seminar

Printing functional materials
Jennifer A. Lewis, Thurnauer Professor of Materials Science and Engineering, Chemical and Biomolecular Engineering, University of Illinois
The ability to pattern functional materials in planar and three-dimensional forms is of critical importance for several emerging applications, including energy harvesting, self-healing materials, and tissue engineering scaffolds. Direct-write assembly enables one to rapidly design and fabricate materials in arbitrary shapes without the need for expensive tooling, dies, or lithographic masks. Recent advances in microscale printing will be highlighted, including omnidirectional printing of flexible microelectrodes, pen-on-paper electronics, conformal printing of 3D electrically small antennas, and printed origami of lightweight metallic and ceramic structures. Ongoing efforts to scale up our filamentary printing approach to enable manufacturing of large 3D structures will also be highlighted.
